The search engine giant has published the source code in order for the app to serve as a template for other Android software.

The company has also revealed the number of features, APIs and design approaches that went into the app, including "Fragments, Loaders, Services, Broadcast Receivers, alarms, notifications, SQLite databases, Content Providers, Action Bar, the Navigation Drawer, the Google Drive API, Google Cloud Messaging, material design, the Android L Preview APIs and Android Wear integration."

Google has also confirmed that the app has been rebuilt to work with JSON files instead of a specific API so that it can be repurposed for other conferences.

"We are excited to share this source code with the developer community today, and we hope it will serve as a learning tool, a source of reusable snippets and a useful example of Android app development in general."

Google also plans to publish technical articles related to the source code and will update the app within the next few months.
